Use this mount to hold your model rockets for display or work! Both the large and small V mounts will hold most low and mid power model rockets. You can also use the 10mm or 20mm extensions if you need more room for fin clearance or otherwise. I recommend the BPS branded base, but feel free to use the non-branded mount, or add your own logo to the STL file!

If you want to design your own top component to fit on the base, I recommend using the CAD drawing in the photos for reference. Start with a 30mm square, add 4 evenly spaced 3.5mm holes between the center and each edge, put one in the center and extrude 5-10mm. Then chamfer the corners 5mm to exactly match the base and you're all set. Let me know if you have any questions!
